Description

Technical Field

[0001] This utility model relates to the field of cable-stayed tower steel cable technology, and more specifically, to a cable-laying device for cable-stayed tower construction. Background Technology

[0002] Cable-stayed tower cables refer to the steel cables connected to both sides of the cable-stayed tower, used to maintain the connection and stability of the entire bridge.

[0003] When connecting steel cables to cable-stayed towers, a cable reel is used to lay out the cables, allowing them to be stably pulled out for connection. However, the diameter of the rod that passes through the hole in the existing cable reel is fixed. Therefore, if the diameter of the rod is smaller than the hole in the cable reel, the gap between the inner wall of the hole and the rod will cause the cable reel to easily shift and sway during rotation and traction. Utility Model Content

[0004] The purpose of this utility model is to provide a cable laying device for cable-stayed construction, which solves the problem that when laying out a cable reel, if the rod of the cable laying reel is smaller than the diameter of the cable reel hole, a gap will be generated between the inner wall of the cable reel hole and the rod, which will make the cable reel prone to displacement and shaking when it is rotated out.

[0008] Preferably, the telescopic rod is a round rod that fits into the groove at one end of the connecting rod, and one end of the telescopic rod is connected to the groove at one end of the connecting rod by a spring.

[0009] Preferably, the deflection shaft is a round shaft protrusion located on both sides of one end of the telescopic rod.

[0010] Preferably, the bonding assembly includes a bonding plate, a hinge block, and an elastic plate. The bonding plate is connected to one end of the telescopic rod, the hinge block is disposed on one side of the bonding plate, and the elastic plate is disposed on both sides of the elastic plate.

[0012] Preferably, the hinge block inner wall groove is connected with the deflection shaft through a torsion spring.

[0013] Preferably, the elastic plate is a part made of elastic metal on both sides of the fitting plate, and the elastic plate and the fitting plate are integrally arranged in an arc shape.

[0014] The technical scheme of the utility model has at least the following advantages and beneficial effects:

[0015] 1. The fitting plate arranged in the device can be deflected and displaced to contract, so that when the steel cable disc is placed, the deflection shaft can be better connected with the steel cable disc hole according to the aperture of the steel cable disc, and displacement shaking during rotation is avoided due to the gap.

[0024] At the same time, when the cable disc is placed by hoisting, the center hole of the cable disc is aligned with the rotating roller 2, and if the hole diameter is greater than the rotating roller 2, the fitting plate 202 will be forced to deflect along the telescopic rod 2011 through the hinged block 2021 when the hole is lowered along the rotating roller 2, so that the fitting plate 202 can be fitted into the inner wall of the hole of the cable disc to support it, preventing the cable disc from being displaced due to rotation when it is pulled out, causing the pulled-out rope to shake.
